Layout considerations for a scalable multi-channel simultaneous sampling data acquisition system (DAS) based on the 16-bit 8-channel DAS AD7606
STM32 Nucleo Kit of IO-Link Masters with IO-Link v1.1 physical layer and stack
The overall structure of this design is roughly composed of a main control module, a current signal sampling module, a power module and a serial port output module. In this article, the main control chip uses a microcontroller model STM32F103RC, which makes the structure as small as possible while ensuring the current sampling accuracy. It is as simple as possible, avoids complex and changeable circuit layout, is more convenient for PCB board production, and is relatively low-cost. Among them, in the design of the sampling conditioning circuit, a current transformer is used to sample the current signal.
MAXREFDES1255 is a 4-switch buck-boost converter that gives a positive step-up/stepdown output voltage.
